well i know that the 212/218 has been a well proven cam for the 4x4s.. i have it and i love it.. but i just feel like my top end isnt that great so since i have a great cousin mechanic that helps me work on my truck i decided to change it to something slightly bigger.. i will be going 6.0 in the later future but this cam was given to me from a friend who was going to put it on his 5.3 and went 6.0 and bigger cam.. so what do u guys think? my current mods are in my sig.. will it help? anything more then what i have will be great..lol thanks..

 

I've never seen those specs before...I've seen close, such as 218/224 though. What's the lift and LSA, and who's grind is it? If Comp, what lobes? Should work well with your 3200 converter and 4.10 gears given that the rest of the specs aren't off the wall...

 

sorry.. i have a lunati cam.. 212/218 531/531 113lsa and i love the dam thing.. but just feel like i can get more .. the 217/223 549/549 113lsa is also a lunati cam.. i know not many use them but since i loved the first one i thought i would go one step up... not much lift and dont want anymore since im on the ls6 yellow springs...

 

Sounds good, it's refreshing to see someone running something other than a Comp grind lol, glad that Lunati has been working out for you

 

lol thanks. man.. i thought i would try something new and didnt plan on using a verter but after i saw my 60' times i just had to get it now i feel like i can go bigger with the cam not wanted to hear some opinions.. thanks for the quick response.. i feel more confidence doing that swap now..

 

Yea, if you think about it, the specs still aren't as wild as say a TR220 which guys run in 5.3's with 3000-3200 converters all of the time. Sounds like it should be a good combo both on the street and the track...plus, you're one of the few guys who can represent one of those cool Lunati Voodoo skull and cross-bumpstick t-shirts (coolest logo ever)

 

they are pretty close.. the tr 220 is a 551/551/ 112 lsa... anyhow i wish i knew more about cams.. lol y is it that ppl stick with same intake and exhaust? idk i like the less intake and more exhaust and i dont know much lol.... well i hope she just wakes up on the top end because i could really afford more top...

 

It all depends on the setup...basically, without getting too technical, an engine with a free flowing exhaust (lt's with good collectors, big pipes, cutout maybe), in comparison to the intake, can go with a single pattern cam. A longer exhaust duration holds the exhaust valve open longer to help the exhaust gasses evacuate from the cylinder...my setup requires more exhaust duration due to my small collectors and cats...well, used to be cats There's a formula and percentages are involved, but this is the quick explanation

 

I'm interested to see the outcome. Are you going to the track after the swap and retune? I agree that the logo for lunati is badass!

 

lol.. idk but i went with the more exhaust because it was popular..lol and yes will be going to the track the week after.. cam should be installed nov 13th.. should have it retuned around the same time.. i will try to hit the track the week after.. and im going to get it dyno tuned around first week of dec so i will be back to c if that made any difference..
